IMPROVED CLAMPFOR sADDLERs, acc.

who-

The Schedule referred to in these Letters Patent and making part of the same.

Be it known that I, WILLIAM K. RArRrGH, of Rural Valley, in the county of Armstrong, and State of Pennsylvaniafhave, as I believe, inventednew and useful Improvements in Olanips for Saddlers and Shoe- Inakers; and Ido hereby declare the following to be a full and exact description-of the same, reference being had t0 the chawings that accompany and form a part Figure l is a View of the clamp closed.

Figure 2, View of the clain'p with the jaws open.

A, the jaws of the clamp.

B, a shaft lying between the two jaws, as in iig. 2.

C, a small chamber, in arrangement as in fig. 2.

D, a ratchet-wheel, which, together ith the workingcrank E, is iixed firmly on the shaft B.

e, a pawl, the lower end of which, at i, catchesinto the ratchet of the wheel D.

g, a spring, whose force is so exerted as paWl to the ratchet.

h, upper end of the pawl e, and is extended quite through an opening therefor in the rim of the chamber Q, as 'may be seen in iig. 2.

j, pinion on which the pawl e turns.

k, a strap, one end attached to the shaft B; the other to the hinged jaw of the clamp. l

l, a spring, Whose force throws the jaws A apart when desired.

to keep the My invention relates to the manner of holding-,the jaws together when'used, and thedevice for relieving them when it is desired that they should open.

My device for this is the chamber C, ratchet D, pawl e, spring g, and crank E, arranged as set forth.

I do not claim the spring Znor the strap k.

' In use, to bring the jaws A together, the ratchetwheel D is turned, the pawl e holding it atany tension l given it. The strap k being wound on the shaft B, draws the hinged jaw close, as required. To loosen the jaws, take hold of the extension`h, o f the pawl e, and draw it upwards until the ratchet is relieved, when the force of the spring Zforees them apart.

What I claimas of my secure. by Letters Patent, is-

The shaft B, with its ratchet D, the charnber C, A

invention, and desire to presence of two subscribing
